Introduction

Electrical circuits can be wired in a way that combines multiple input conditions into a single output condition. This happens when multiple sensors control a single alarm. or when multiple switches control a single light bulb.

Activity

Complete the Quia activity linked to the right.

Assessment

1 Quality Point

Exercise is attempted with some success.

2 Quality Points

Exercise is attempted, and mostly successful.

3 Quality Points

Exercise is fully successful, regardless of number of attempts.

4 Quality Points

Exercise is supplemented with the PI1 document in my Teachers folder. It will require:

• a screenshot of a PhET Circuit Construction Kit simulation with four switches in a mixed* circuit, different from the ones in the Quia activity; (*a mixed circuit contains both AND and OR features!)
• a completed truth-table for the circuit.

5 Quality Points

Exercise is also supplemented with a screencast, which shows the PhET Circuit Construction Kit operating as shown in the truth table. (Limit your screencast to 30 seconds, please!) Please contact Mr. Cox if you need any assistance making a screencast!
